10-Minute Tech: Simplify Ceiling Grille Removal

Vent Bolts

We love the 8½-foot ceilings in our toy hauler but cannot imagine why anyone would design the air-conditioning return grilles in the ceiling (that contain the filters and are held on with cover screws) so you need to use a screwdriver every time you remove them. Our trailer’s grilles had only two screws, while our buddy’s has six!  We replaced the cover screws with hanger bolts. From there, you can add wing nuts or chrome acorn nuts to ease grille cover removal and air-filter access. And it’s the perfect time to replace the inferior filters with higher quality products.
